Abstract

A charger cradle for recharging a rechargeable lighting device is described. The cradle may include two prongs that flex outwards to allow a lighting device to be inserted into the cradle. After the lighting device is fully inserted, the prongs resume a normal position to exert an inward force on the lighting device to secure it in place. The cradle may also include two moveable cradle arms, in lieu of two prongs, to allow a spring mechanism within the device to motivate the moveable cradle arms to grasp a lighting device when the lighting device is inserted into the rechargeable lighting device.

Claims

1. A charger cradle for recharging a flashlight having a barrel, comprising:

a housing having a bottom base and a support configured to receive at least a first portion of the barrel;

a first electrical contact and a second electrical contact configured for charging the flashlight when the flashlight is inserted into the support;

two opposing rotating cradle arms mounted within the housing, each of which is configured to rotate between an open position and a closed position, each of which is configured with an upper section and a lower section;

a cradle arm stop mounted within the housing configured to engage the lower section of each of the two opposing rotating cradle arms in the closed position and prevent each of the two opposing rotating cradle arms from rotating out of the closed position toward the open position while the cradle arm stop engages the two lower sections of the two opposing rotating cradle arms;

a biasing means for biasing the cradle arm stop upwardly away from the bottom base toward the support;

a release button configured to push down on the cradle arm stop which pushes down on the biasing means to disengage the two lower sections of the two opposing rotating cradle arms and allow the two opposing rotating cradle arms to rotate to the open position until a release button is actuated to disengage the cradle arm stop and thereby allow said two opposing rotating cradle arms to each rotate to said open position;

wherein each of the two opposing rotating cradle arms is configured to receive a second portion of the flashlight when the flashlight is inserted in between the two opposing rotating cradle arms in the open position and lock the flashlight in the charger cradle when insertion of the flashlight into the charger cradle causes said two opposing rotating cradle arms to rotate into the closed position where they are engaged by the cradle arm stop.

2. The charger cradle of claim 1, further comprising an LED to indicate when charging occurs.

3. The charger cradle of claim 2, further comprising a light pipe to transmit light from the LED to a surface of the cradle.

4. The charger cradle of claim 1, wherein the housing includes a cylindrical portion and a flared portion.

5. The charger cradle of claim 1, wherein a printed circuit board (“

PCB”

) is mechanically secured to a top surface of the base.

6. The charger cradle of claim 5, wherein the PCB is mechanically secured to a top surface of the base at two locations.

7. The charger cradle of claim 5, wherein the housing is attached to the base by a plurality of mechanical fasteners.

8. The charger cradle of claim 7, wherein the plurality of mechanical fasteners pass through a plurality of apertures in the PCB.

9. A cradle for a flashlight having a barrel, comprising:

a housing having a bottom base and a support configured to receive at least a first portion of the barrel;

two opposing rotating cradle arms mounted within the housing, each of which is configured to rotate between an open position and a closed position, each of which is configured with an upper section and a lower section;

a cradle arm stop mounted within the housing configured to engage the lower section of each of the two opposing rotating cradle arms in the closed position and prevent each of the two opposing rotating cradle arms from rotating out of the closed position toward the open position while the cradle arm stop engages the two lower sections of the two opposing rotating cradle arms;

a biasing means for biasing the cradle arm stop upwardly away from the bottom base toward the support;

a release button configured to push down on the cradle arm stop which pushes down on the biasing means to disengage the two lower sections of the two opposing rotating cradle arms and allow the two opposing rotating cradle arms to rotate to the open position until a release button is actuated to disengage the cradle arm stop and thereby allow said two opposing rotating cradle arms to each rotate to said open position;

wherein each of the two opposing rotating cradle arms is configured to receive a second portion of the flashlight when the flashlight is inserted in between the two opposing rotating cradle arms in the open position and lock the flashlight in the cradle when insertion of the flashlight into the cradle causes said two opposing rotating cradle arms to rotate into the closed position where they are engaged by the cradle arm stop.

10. A cradle for a flashlight having a barrel, comprising:

a housing configured to receive at least a first portion of the barrel;

two opposing rotating cradle arms held by the housing, each of which is configured to rotate between an open position and a closed position, each of which is configured with an upper section and a lower section;

a cradle arm stop held by the housing configured to engage the lower section of each of the two opposing rotating cradle arms in the closed position and prevent each of the two opposing rotating cradle arms from rotating out of the closed position toward the open position while the cradle arm stop engages the two lower sections of the two opposing rotating cradle arms;

a biasing means for biasing the cradle arm stop from the open position to the closed position;

a release button configured to push down on the cradle arm stop which pushes down on the biasing means to disengage the two lower sections of the two opposing rotating cradle arms and allow the two opposing rotating cradle arms to rotate to the open position until a release button is actuated to disengage the cradle arm stop and thereby allow said two opposing rotating cradle arms to each rotate to said open position;

wherein each of the two opposing rotating cradle arms is configured to receive a second portion of the flashlight when the flashlight is inserted in between the two opposing rotating cradle arms in the open position and lock the flashlight in the cradle when insertion of the flashlight into the cradle causes said two opposing rotating cradle arms to rotate into the closed position where they are engaged by the cradle arm stop.
